And is that more-or-less true of gdb as well? I.e., if host/target

Native gdb yes. A 32-bit GDB should still be able to debug a
remote/gdbserver 64-bit inferior.
Actually, I phrase it as a question even though I am pretty sure it
is true. My real question is "Why?". It seems to me that if we just
included amd64-linux-nat.o and amd64-*-tdep.o in the build, then
32-bit gdb should be able to debug 64-bit native apps.
Wouldn't work. The limitation is on ptrace.
